IMPROVEMENT IN' WINDMILLS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom'fit may conce/rn: K

Be it known that I, 11.1%.. MACoMBnn, of Shopiere, vRock county, Wisconsin, have invented a new and improved Windmill; and I do hereby declare that the following is Ia full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, in which- Figure 1 is a side view or elevation;

/Figure 2 is a vertical section;

Figure 3 is an under-side view of the operating-part of the mill; and

Figure 4 is also an under-side View, similar to fig; 3.

The nature of my invention consists- First, in so pivoting the wings of a windmill that lthey, while travelling with the wind, shall be opened or distended by it, to receive' its full force; and, while returning, on the opposite side of the mill, against the Wind., they shall be closed or collapsed by it, so as thereby not to retard the mill, substantially as hereinafter more fully described.

Second, in attaching the outer ends ofthe pivoted wings of a windmill, by means of cords or other suitable device, to a Wheel turning freely on the main shaft of the mill, and provided with a brake and stops, in such a manner that the application of the brake, by stopping the wheel, shall close or collapsethe Wings, and thereby stop the mill, while the extension ofthe wings by the wind, or the collapsing 'thereof by the brake, is adjusted o1' regulated by Vthe stops, substantially as hereinafter described.

In -constructing my Windmill, I pivot the wings a, af, (1,2, dto., to the circular heads or .plates A'B, that are secured together by the cross-pieces V, iig. 2, and that are firmly attached to the shaft F, to which is secured the gear-wheel or pinion Gr, that may, as desired, be used to operate any kind of machinery.

The shaft F plays in the boxfbearings H I, attached to the standard R of the supporting frame-work K L N.

Below the wings, and freely playing on the shaft'F, is a wheel, C, that, at equidistant points, is attached, by the cords c, to the outer ends l) of the Wings, as. more fully shown in figs. 3 and 4.

The brake P is attached to and takes fulcrum in the brace Nl of the frame-work, and works on the circular rim E of the wheel C.

Attached to the under face of the lower head or plate, B, by screws or otherwise, is a segmental piece, D, that is pierced radially with a series of orifices, in which are fitted the sliding bolts or stops j, f1, f2, Sac., that are slid in and out, (that is, toward and from the the pins i, that play in mortises in the part D; as shown in iigs. 3 and 4'. These sliding bolts or stops work in connection with the pin l1., that projects from the outer face of the wheel C.

In operating my windmill, if it is desired to allow the mill to run, the brake P is loosened, when the action of the wind causes the wings-on one side of the mill to open or distend, while those on the other side are closed, and kept closed until, by the revolution of they, in turn, are opened andthe former closed, as shown in figs. 1, 2, and 3.

If it is desired to stop the mill, the brake P is applied to or pressed against the circular rim E of the wheel C, (as shown by dotted lines, P', figs. 1 and 2,) thereby causing it tolstop, or retarding its motion, so as to draw in, by means of the 'cords c, the wings to the position shown in fig. 4, when the mill stops.

It willbe seen, by reference to figs. 3 and 4, that as the brake P is loosened, the wings continue to open or distend until the pin h strikes the bolt or stop that is slid inor toward .the shaft, (as shown by j in fig. 3,) and that, as the brake is applied, the Wheel C is stopped, and the wings continue to close, until the pinh strikes the stop that, at the other end of the segmental piece D, may be slid in, (as shown by j'4 in fig. 4,) and that, consequently,.the degree of the opening or extension of the win gs, as well as the closing thereof, can be fully regulated by sliding in or out whichever of the stops, f, f, Sto., may be desired.

The' pivoted wings a, a, a2, &c., the cords c, the loose Wheel C, provided with the pin h, the segmental piece D, provided with the sliding stops f, f, f, &c.,

substantiallyk as and for the purpose described.

shaft F,) as well as retained in position and guidedby the wheel, they exchange places with the former, when and the brake P, when the whole are arranged and used
